> How could the ‘secret’ link end up in the wrong hands? Some possibilities:
1. An email thread / document with a link to the photo or album is forwarded or shared with the wrong person, or accidentally posted somewhere public.
2. The recipient naturally thinks the link is only works for them (as would be the case for Drive) and doesn’t take care to prevent it becoming public.
3. Links sent by emails are semi-public because they move across the internet unencrypted and are simple to intercept. It’s only OK to link to sensitive things by email if the recipient needs to be logged in to actually view them.
4. A database of these links is one day leaked or hacked, or people figure out a pattern in how the ‘secret’ URLs are generated.
5. Someone’s emails or other documents are hacked or leaked, with the link in them.
